The Cost of Pharmaceutical Products used by Shift Workers (and Others Too!)

President Obama has made the decision to tackle skyrocketing health costs and pass real health reform this year. While spiraling health care costs are regularly reported in the press and employers are certainly concerned, they are not always a household priority, unless the family doesn't have employer sponsored health insurance - which is becoming more common given all the recent company layoffs.


Most families are more likely to regularly lament over the increasing cost of food. And food has most certainly become more expensive. Over the past several years, U.S. food prices have risen faster than at any time since 1990. Prices for all food purchased in the U.S. increased 5.5 percent in 2008, and 4.0 percent in 2007, up from a 2.4 percent increase in 2006. But think of this: in 2007 the total U.S. health care bill came to $2.3 trillion - more than we spent that year on food. The United States spent approximately 16 percent of its 2006 gross domestic product on healthcare, up from eight percent in 1975.


Without reform, the Congressional Budget Office projects that health expenditures will increase to 25 percent of GDP by 2025. Health care spending among other rich, developed countries in the Organization for Economic Cooperation and Development averaged just nine percent of GDP in 2006. According to a report by U.S. PIRG, health care spending rose 56 percent from 2000 to 2006, versus an inflation rate of just 18 percent and wage increases of 20 percent. This forced employers to choose between reducing benefits, limiting pay increases and hiring fewer employees.


The PIRG report cites "unproductive spending: overuse of invasive treatments, intensive services, and hospitalization, excessive administrative costs, and prescription drug marketing that encourages the use of more drugs, more expensive drugs" as the main reasons for the excess costs. PIRG has some good points, but the fact is that our "healthcare system" is primarily disease-care driven versus prevention oriented. Life expectancy continues to increase but at great cost. Last year, 95 cents of every medical-care dollar went to treat disease after it had already occurred.


At least 75 percent of these costs were spent on treating chronic diseases such as heart disease and diabetes which are preventable or even reversible. 133 million Americans, representing 45 percent of the total population, have at least one chronic disease and chronic diseases kill more than 1.7 million Americans per year and are responsible for seven out of ten deaths in the United States. President Obama clearly has been educated about our prevention focused deficits. That's why he's seeking $684 billion over the next ten years for health care reform and he's said that a good percentage of this should go to preventative care.


So, what does this mean for shift workers and shift work employers? There are certain diseases that are more prevalent among shift workers than the rest of the population. While all employee populations are important, zeroing in on this group of workers will provide an employer more bang for their buck, meaning greater cost reduction return from prevention investment. While spending on doctors and hospitals makes up over 56 percent of our health care spending and prescription drugs account for only one-tenth of total health-care expenditures, what the drugs are prescribed to treat is easier to capture than what the doctors are spending their time on.


And since spending in the U.S. for prescription drugs was $201 billion in 2005, almost five times more than the $40 billion spent in 1990, it can provide a good window into recent healthcare trends. From 1997 to 2007, the number of prescriptions purchased increased 72 percent (from 2.2 billion to 3.8 billion), compared to a U.S. population growth of 11 percent. Looking at spending on drugs gives an interesting window into what diseases doctors are treating. Reviewing data from Drugs.com, approximately $156 billion was spent on prescription based pharmaceutical products in the U.S. in 2007.


This is what was spent on the top fifty grossing drugs (representing $80 billion or roughly half of the total spent) by focus of the treatment:

  • Mental health - $21 billion

  • Heart - $20 billion

  • Gastrointestinal - $11 billion

  • Lung - $9 billion

  • Diabetes - $6 billion

  • Pain - $4 billion

  • Bone density - $2 billion

  • Sleep - $2 billion

  • Others - $5 billion

  • Total - $80 billion

Correlating this list to the highest health risks of shift workers provides amazing results.  
 

  1. Obesity - 71 percent of male and 53 percent of female shift workers are overweight, compared to 59 percent of males and 51 percent of females overall. 26 percent of male shift workers are considered obese versus 19 percent overall.    

  2. Cardiovascular health - Shift workers are 1.4 times more likely to have cardiovascular problems than daytime workers.    

  3. Gastrointestinal disease - Shift workers are 2.3 times more likely to suffer from gastrointestinal disease (especially heartburn and indigestion) than daytime workers. Stomach disorders are four to five times more common with an eight-fold increase in gastric ulcers.    

  4. Excessive sleepiness - 60 percent of shift workers report feeling fatigued, drowsy or sluggish at work at least several times a month and almost half report fighting sleep or nodding off at least several times a month while at work. 60-80 percent of shift workers complain of chronic sleep disturbances.   

  5. Musculoskeletal complaints - More than 30 percent of shift workers report chronic or frequent back problems and nearly 30 percent report chronic leg problems.   

  6. Depression - While the data is not complete, a number of studies have found an increased prevalence of depression among shift workers, particularly those working rotating shifts or permanent nights.

What should companies do to address these chronic health issues?

  • Working with your external health providers and your human resource management system, perform an analysis of health care costs by operating location and by shift, if possible. Focus on the eight major categories driving health costs (mental health, heart, gastrointestinal, lung, diabetes, pain, musculoskeletal and sleep).  Compare and contrast locations and shifts to determine which ones are the most costly and which cost the least (for each of the eight categories).
  • Consider anonymously polling employees to zero in on the work environment, personnel profiles, and work schedules of the most costly environments as compared to facilities/departments with the lowest health costs.
  • Reassess the overall work schedule of each costly facility/department. Look at the speed of rotation (how often does the schedule change), the direction of rotation (forward or backward) and the length of shifts. Try to determine which schedules best fit the employees' lifestyles while also meeting company goals.
  • Review individual employees' work schedules at the most costly facilities/departments.  Some industries have moved to flexible staffing with the schedule being self selected by the employee. While the flexibility is good for employees trying to balance work with life and family, some employees may not select a healthy schedule. Working too many hours, too many consecutive days without adequate recovery periods and selecting randomly patterned work hours are eventually likely to result in health problems.
  • Evaluate the success of health prevention and wellness programs offered against the known health risks above, the workers' complaints (if you've polled the workers) and the investment made in each program. Reorganize health prevention and wellness programs as necessary.
  • Perform regular reviews of costs incurred against programs offered to make sure that improvements in health prevention are happening.

Meanwhile, researchers at Brigham and Women's Hospital in Boston continue to study ways to reduce the costs of prescription drugs. One proven method of cost reduction is the use of formularies, a pre-approved list of prescription drugs. In plans with formularies patients are charged the lowest co-payment for generic medications. Doctors using e-prescribing with formulary decision support increase the use of generic prescriptions by 3.3% (see December 8, 2008 Archives of Internal Medicine for this study).


The study estimates that the use of e-prescribing systems with formulary decision support could reduce prescription drug spending by up to $3.9 million per 100,000 patients per year.
