Healthcare Big Data – Part 2a

Big Data 3Vs cardboard-box-iconIn the post Healthcare Big Data – Part 2 (this link will open in a new tab of your current browser window), I wrote that no matter the size of Healthcare Big Data, a known fact of the current state of healthcare industry worldwide which is in general afflicted with poorly coordinated care, fraud and abuse and administrative and clinical efficiency, the goal is ultimately to improve patient care and reduce costs.

In this post I like to share with you this infographic below (click on the image of the infographic below to view a larger image which will first open  in a new tab of your current browser window, click again on the image in this new tab which will then show you a full view of the infographic in the same tab) which I think rightly supplements what I wrote in the post mentioned above.

This infographic visualises the worldwide trend to digitize healthcare patient information from paper-based medical records to Electronic Medical Records. This trend continues to gather increasing momentum to produce infinite volumes of Big Data, an estimated 50 pentabytes of data in the healthcare realm. This influx of Big Data will create more jobs to handle all these data, especially new jobs that demand new talent in analytics,

This infographic also visualises the bulk of the internal source of Healthcare Big Data as originated by medical providers and ancillary services providers during the course of providing their services. More Big Data is accumulated when these internal data source is in turn used for insurance claims and payments, to a greater extent In advanced economies and lesser in less advanced economies. The technology vendors provide the technology interface for the internal source of Healthcare Big Data.

Then there is the external and public as well as private storage of Healthcare Big Data. Public Health agencies also generate Healthcare Big Data mandated by legislation and regulations e.g. immunisation and cancers data, and store them in data repositories. Third-party organisations also generate Healthcare Big Data when they coordinate between healthcare providers. Private data are also stored in remotely stored and web-based repositories when some consumers maintain personal (private) health records online.

From this infographic, patient care is improved when streaming data is used to decrease patient mortality as these data moves in healthcare. However the bigger challenge is to harness the 80% of all the unstructured data of patient information in Healthcare Big Data.

When it comes to healthcare Big Data is a Big Deal

I shall discuss the ways of Big Data which will transform healthcare, in the near future with cost savings, quality of care, and care coordination after I have blogged about Big Data solutions in a future post.

Healthcare Big Data – Part 2

Big Data 3Vs cardboard-box-iconIn this second instalment of Healthcare Big Data, let’s look at the multiple sources of data that are responsible for Healthcare Big Data.

The internal data found in existing paper-based medical records is one large source of Healthcare Big Data.

With more and more hospitals in the health care industry around the world turning to creating digital representations of existing data in paper-based medical records and acquiring everything that is new in the form of Electronic Medical Records, there is an infinite data growth rate in this internal data source.

Then there is also Big Data from other sources, those from external, private, and public sources.

The discovery process, both oral and written discovery initiated by the legal profession outside the healthcare industry which adds terabytes or even petabytes of information is one source of external Healthcare Big Data, when individual doctors, hospitals, and medical practice groups become defendants in malpractice lawsuits.

No matter the size of Healthcare Big Data, a known fact in healthcare is to improve patient care and reduce costs.

Thus to improve patient care and reduce costs through Healthcare Big Data, one of the biggest challenges for most healthcare organisations is to mine the data or dig for something of value from these multiple sources of data. Healthcare organisations must find i.e locate the appropriate data, identify useful data i.e determine whether the data set is appropriate for use,  and aggregate all of the Big Data from the multiple sources and push through an analytics platform as part of their analytics processes.

Since I am running a blog for the general benefit of Health Information Management (HIM) / Medical Records (MR) practitioners, I shall not be diving deeper into big data sources, to avoid driving readers into the IT realm nor writing on the business analytics (BA) and business intelligence (BI) processes to determine how large-scale data sets can be used. I must say that all the posts on Big Data I have published on this website-blog , including this one is to facilitate HIM / MR practitioners to have a rudimentary understanding of Big Data.

Now that HIM / MR practitioner readers  know that Big Data is out there, Frank (2013) states that “analytics is part science, part investigative work, and part assumption.” The idea is to capture as much as data the healthcare organisation deals with, so all of any data are located, included and gathered from as many data sources as possible so that the more data there will be to work with and bring all of these data into an analytics platform.

While the healthcare organisation locates, includes and gathers from as many data sources, healthcare organisations will find a vast wealth of external public information. This external data makes up the public portion of Big Data. This includes customer sentiments from research companies and social networking sites e.g Twitter, Facebook to geopolitical issues e.g. weather information and traffic pattern information, from government entities, e.g census data, and a multitude of other sources.

In the next instalment, I shall gather more information on how the multitude of sources of Healthcare Big Data must be integrated and managed to set priorities so that Big Data solutions could analyse and get the results into the right hands to improve patient care and reduce costs.

JCI Standard MCI.7 – Medical Records contents sharing

Medical Records continue to be a primary source of information containing patient-specific information to provide effective care, develop treatment guidelines, determine ability to pay for care, bill third-party payers, and anonymously conduct research studies. Any hospital must maintain a medical record for each inpatient and outpatient. It needs to be available during inpatient care, for outpatient visits, and at other times as needed and it must be up to date to ensure communication of the latest information. Thus, the medical record containing medical, nursing and other patient care notes is an essential communication tool that is useful to support the continuity of the patient’s care and must always be available so that it can be shared among all of the patient’s health care practitioners at all times.

Since the Medical Record is always available to all the patient’s health care practitioners, a hospital must create written privacy policies and procedures, which clarify who has the right to access protected information, how protected information will be used within the covered entity, when protected information may be disclosed, and employees must be trained on such privacy policies and procedures to ensure confidentiality of patient information.

An example when written privacy policies and procedures must be created is epitomized  in the Health Insurance Portability and Accountability Act of 1996 (HIPAA) in the United States of America.

Electronic Medical Records (EMR) like paper based medical records, must also be available to all the patient’s health care practitioners. In order to maintain patient confidentiality, the patient’s health care practitioners must be granted need-to-know status to gain access to the EMR. However there are exceptions, like when attending and resident doctors who are involved in current treatment episodes or on an emergency basis can also gain access through a security override feature incorporated into the EMR system.

It is very important that when all of the patient’s health care practitioners and/or other employee or medical staff member are granted access to the EMR, he or she receives training on system security, appropriate access to and utilisation of patient information, password protection features, existence of audit trails and access monitoring, and consequences of inappropriate access and/or most importantly, breach of patient confidentiality.

Many hospitals also require that their employees and medical staff members sign a statement indicating that they understand the confidential nature of patient information and the need to keep the information and their password secure.

Thus, every hospital must, regardless of its level of computerisation, need to have a comprehensive information security policy which defines the hospital’s commitment to confidentiality for patients, members of the community and its employees. It provides a blueprint for defining standards and procedures and it establishes a standard of care with respect to the handling of its confidential informational resources. A confidentiality committee with the task of developing a comprehensive information security policy should be appointed by the hospital’s leaders.

The issue of confidentiality is so important so much so that a preprinted confidentiality statement on the outside of the medical records file folder usually alerts users that patient information in the medical record is confidential and cannot be removed from the facility without proper authority.

If you are a Health Information Management (HIM) / Medical Records (MR) practitioner practising at a hospital which is already Joint Commission International (JCI) accredited or seeking JCI accreditation status or undergoing re-survey for JCI accreditation status, then he or she must be aware that the JCI Standard MCI.7 requires that “The patient’s record(s) is available to the health care practitioners to facilitate the communication of essential information.”

In all instances, the HIM / MR department at any type of hospital is responsible for allowing appropriate access to patient information in support of clinical practice, health services, and medical research, while at the same time maintaining confidentiality of patient and provider data.

This is also true when the  HIM / MR department at a hospital which is already JCI accredited or seeking JCI accreditation status or undergoing re-survey for JCI accreditation status, is responsible to collect medical records selected and for allowing appropriate access to patient information in support of a Medical Records Review session.

To end, HIM / MR practitioners  please take note that the JCI Standard MCI.7 is among the five (5) JCI MCI standards within the Communication Between Practitioners Within and Outside of the Organisation block of the JCI MCI Chapter.

APDC: Spotlight on burns

ICD-10-book-cover-for-APDC-series-labelBurns are common conditions seen in the Emergency Room (ER) / Department (ED) when a traumatic injury results in tissue loss or damage on body region(s). Caroline and Mary (2012 p. 1206) classify burns “according to the mechanism of injury and according to burn depth and size”,

An example of an ER / ED case is when a 56 year old man presents with an  electrical burn while undertaking mechanical repairs to his car when his metal wrist watch had made contact with part of the electrical system. Although electrical burns can be potentially life threatening, especially if caused by electric shocks due to exposure to electricity current or lightning, this patient experienced immediate pain from an injury to the radial aspect of his right wrist with subsequent skin changes and discomfort at the periphery of the lesion.

The ER / ED doctor will assess to estimate the total body surface area and depth of this burn as seen from the photograph (left), and manage this ED / ER case.

Other common examples of burns seen in the ER / ED are thermal burns as a result of direct contact with heat sources – example caused by steam, hot water scalds, and flames, electrical burns as well chemical burns caused by exposure to strong acids,
alkalis, or other substances such as detergents or solvents especially affecting the skin and eyes, and radiation burns from exposure to radioactive sources, such as the ionizing radiation used in industry, or therapeutic radiation.and sunburns.

The International Classification of Diseases (ICD), 10th Revision: Version 2010 provides several codes to classify burns.

Burns are classified under the Chapter XIX Injury, poisoning and certain other consequences of external causes (S00-T98) and spread across three (3) blocks, from T20 to T32.

From within the codes from T20 to T32 for burns under the Chapter XIX, they are grouped into three (3) groups, namely codes from burns of external body surface, specified by site (T20-T25) – example of a site is the head and neck site, to burns confined to eye and internal organs (T26-T28), and burns  of multiple and unspecified body regions (T29-T32).

Health Information Management (HIM) / Medical Records (MR) practitioners must take note that when the site of the burn is unspecified but the burn is  classified according to extent of body surface involved, then the codes from T31 category is to be used as the primary code only . However, it may be used as a supplementary code, if desired, with categories T20-T25 or T29 when the site is specified. 

Image credit: TBSA rule of nines, Caroline and Mary (2012 p. 1208)

Doctors who record the assessment for burns use some modification of the “rule of nines” (as above) for estimating percentage of body burned from the total body surface area (TBSA). The body is divided into multiples of 9%. For instance, one arm equals 9% and the entire back equals 18%.

HIM / MR practitioners must also be aware of the codes assigned to sequelae (a residual condition) of burns, corrosions and frostbite at T95.

Nutrition therapy and the medical record

Patients are screened for nutritional risk as part of the initial assessment with the application of screening criteria to gather information on nutritional status or functional status – often done by nurses, which must also be completed routinely within 24 hours of admission to the hospital or at an earlier time period.

I had covered at length on this requirement as you can follow from the posts (each of the following links will open in a separate new tab of your current browser window) Hospital screening criteria data to identify patients with nutritional or functional needs and 6 steps in documenting hospital screening to identity patients with nutritional or functional needs.

A patient identified with nutritional or functional needs i.e. at nutrition risk, is referred to a nutritionist for further assessment and a collaborate plan for nutrition therapy is carried out by doctors, nurses, and the dietetics service, and when appropriate with the help of the patient’s family. The nutritionist monitors at intervals the patient’s progress from the nutrition therapy, the nutritionist’s reassessment throughout this special care process is part of all reassessment by all the patient’s health care practitioners as the key to understanding whether care decisions are appropriate and effective, and records the progress in the patient’s record.

So what is nutrition therapy?

A patient is after a burn or surgery. Another patient is with a high fever, or suffering from acute diarrhoea. Yet another patient is with diabetes mellitus, a disorder throughout life. One other patient is suffering an acute illness with coronary or vascular disorders.

Nutrition is a vital component of therapy for the above listed disorders. According to (eds. Catherine, Benjamin, Robert, Katherine, & Thomas 2014, p. 1162), “use of the term therapy recognizes the role of nutrition in affecting patient outcome and acknowledges the demonstrable risks and benefits to nutrition intervention in both the short term and the long term.”

So, nutrition therapy is required with a high protein intake to rebuild, repair and heal body tissues after a burn or surgery. Nutrition therapy is provided when a patient needs fluids and electrolytes to replace what is being lost due to haemorrhaging, vomiting, and perspiring profusely. Because most serum glucose depends on dietary intake, nutrition therapy is a vital component in the prevention and management of diabetes mellitus which necessitates a special diet plan. Nutrition therapy  is again necessary with a special diet limiting or modifying the fat and sodium intake for a patient with coronary or vascular disorders.

Thus, Health Information Management (HIM) / Medical Records (MR) practitioners will find within medical records, progress notes with the nutritional care of the patient met in accordance with the doctor’s orders which includes the nutrition therapy, and the patient’s progress from the nutrition therapy documented by the nutritionist.

I think medical records will only be complete if a patient at nutrition risk undergoing nutrition therapy has his or her medical record showing progress notes from the nutrition therapy documented by the nutritionist. This particular instance of medical record completeness must be satisfied irrespective of your type of hospital, either it is or it is not already Joint Commission International (JCI) accredited or seeking JCI accreditation status or undergoing re-survey for JCI accreditation status, but if it is, then your hospital will need to comply with JCI Standard COP.5 which requires that “Patients at nutrition risk receive nutrition therapy.”

If JCI Standard COP.5 and its four (4) Measurable Elements are complied satisfactorily, then your medical record also complies with the JCI Standard MCI.19.1 which states that “The clinical record contains sufficient information to identify the patient, to support the diagnosis, to justify the treatment, to document the course and results of treatment, and to promote continuity of care among health care practitioners.”

Before I end, some of you may be wondering what’s the difference between a dietitian and a nutritionist? I am not going to elaborate much on this but since I have used the terms dietitian and nutritionist in three related posts on nutrition I know for certain that dietitians and nutritionists are both food and nutrition experts respectively. You may find out more on dietitians and nutritionists from the Academy of Nutrition and Dietetics (United States) and from the University of Maryland Medical Center, United States. Some say dietitians are considered to be nutritionists, but not all nutritionists are dietitians.
