Maine Hospital Quality Snapshots

Geographical Medical Variation Charts

Maine has been divided into 32 regions known as healthcare service areas (also called Hospital Service Areas) based upon hospital towns and locations where most people receive their hospital-based services. The maps you see are showing differences (statistically significant) between different HSAs in the state. The maps are organized by procedure (e.g. lumbar fusion surgery) or by admission to hospitals for particular medical conditions (e.g. digestive medicine).

For example, if you select Lumbar Fusion Procedures you will see that the Lewiston Spine Service Area is consistently higher than expected. Because this consistent pattern may indicate a treatment philosophy that favors lumbar fusion for back pain those who received their care for low back pain in this region appear far more likely to have lumbar fusion recommended. If you or a loved one are suffering with low back pain and you live in this area you may wish to receive your second opinion from a provider within a different region.

Variation in admission rates for medical conditions is different. Generally, these admissions are related to chronic illnesses that can be managed successfully outside of hospitals. In regions where the admission rates consistently are higher than expected the Maine Quality Forum suggests that the communities in those HSAs begin discussions about why? A great place to start these conversations is with local Healthy Maine Partnerships, business organizations, service organizations, and chronic illness support groups. Of course, another great place to start is with your primary care provider.

The data is all obtained in these charts from the hospital inpatient discharge database maintained by the Maine Health Data Organization. MHDO Website

We have presented all of the variation charts in the same way. The title describes the surgical procedure or activity displayed in the chart and the date range for the information listed.

The vertical axis lists the HSAs or the Specialty Care Regions. We do not use the York HSA because too many citizens of that area get their care in New Hampshire. Therefore, for York this method does not work.

For variation charts, the horizontal axis is the percent difference or variation of each HSA from the state mean or average (at 0%). Positive differences are shown in bars to the right of 0% and negative differences are shown to the left of 0%.

For rate charts, the bars represent the rate for the HSA or Speciality Care Region and a vertical line marks the Maine state average rate. Labels on bars indicate the 95% confidence intervals for area rates (or the highest or lowest their actual rates might be when you take into account random errors in sampling that might affect estimations of rates).

Quality Analysis Charts

We have presented all of the quality analysis charts in the same way. The title describes the topic and the year of the data. The vertical axis is the rate of the topic presented. We use confidence intervals in these charts. Larger confidence intervals suggest smaller sample sizes or fewer hospitals in the peer group in these charts. The blue horizontal lines represent the state average confidence intervals. To be comfortable saying that a data point is truly different from the state mean the confidence intervals cannot overlap.
